LTDC interrupt routine is used to reload frame buffer pointer
once full frame is finished flushing. As long as there is no
need to change buffer - there is no need to disturb CPU.
Thus: Enable LTDC interrupt only when new buffer is pending

The LTDC RGB565 format corresponds to the PIXEL_FORMAT_BGR565 format.
Update the LTDC driver to advertise PIXEL_FORMAT_BGR565 as the supported
format instead of PIXEL_FORMAT_RGB565. This change ensures correct color
rendering in the sample display application and enables usage of the
video capture sample application.

display_rm67162 uses mipi_dsi API(s) to update transfer frame data, some
low level IP can while some cannot handle non-contiguous buffer(the frame
pitch is larger than frame width). In this case, pass the frame descriptor
as the user data in the message to the low level driver and let it
handle how many data to send. The display_rm67162 driver only need to
set the address correctly for each transfer according to the pitch/width.

Comments and documentation mention compatibility with several
Sharp LS0xxx references, such as LS012B7DD06, a 64-color 6-bit
parallel display, and LS013B7DH06 a 8-color serial display.
The ls0xx driver supports serial and monochrome only.

The LED_STRIP driver is not enabled by default on all boards. As a result,
building the LED_STRIP_MATRIX display driver fails if LED_STRIP is not
manually enabled.
To address this, this commit changes the dependency from `depends on` to
`select`, ensuring that the required driver is automatically enabled and
build failures are avoided.

The display_blanking_on description states that if available,
backlight should also be disabled / enabled on driver blanking on / off.
Moreover, upon driver initialization, the display blanking (hence
backlight state as well) should be same as if display_blanking_on
had been called.
If nothing can be done by the LTDC driver (no backlight and no
panel blanking) then -ENOSYS is returned.

Theoretically (if either `height` or `width` in `config` is set to 0),
the `ret` variable might be returned from `st7567_clear()` without
being initialized.
Add initialization of this variable to avoid compiler warnings.
